DUPLICATING-MACHINE.

To all whom it may concern:

Beit known that I, JAMES GERALD DAILEY, citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Duplicating-Machines, of which the following is a specification.

My invention relates to improvements in duplicators such as are used for making manifold printed copies from type, inked by means of a cloth or ribbon which dispenses the ink.

The objects of my invention are, 1-to f provide a duplicator by which any number of prints may be obtained. 2to provide a duplicator by' which the best quality of printing may be obtained. S-to provide a duplicator which automatically disposes of the rinted sheets, piling them in correct relation to each other. 4-to provide a duplicator in which there is no lost motion as every trip of the carriage in either direction produces a printed copy. I attain these objects by the mechanism illustrated in the accompanying drawings, in which,

Figure 1 is a perspective view of my improved duplicator, F ig. 2 is a sectional view of the tumbling rod and rests, Fig. 3 is a perspective of a duplex bearing for the ribbon spools. Fig. 4 is a longitudinal sectional view of duplicator. Fig. 5 shows a detail view of the ribbon mechanism, also a modified form of the means for operating the tumbling rod. Fig. 6 is a sectional view of Fig. 5 taken on line c-a. Fig. 7 is a detail view of the tumbling rod showing the paper rests in two positions, one in dotted lines. Fig. 8 shows a bed plate in connection with a modified form of tracl beams, with a roller mounted thereon. Fig. 9 shows a sectional view of a galley.

Suitable characters designate similar parts throughout the drawings, in which,

1 is the basal member, comprising a cabinet having drawers in the rear, the top drawer being for the purpose of containing printers furniture, tools, etc., and the two lower drawers or type cases for type.

The sides 5 and the back 6 of the cabinet, extend upward forming a ledge, bounding three sides of the top surface of the cabinet.

A printing frame 7 is pivoted to the ledges 5 at 8 and connected to the ledge 6 by the braces 9 which are hinged to and Specification of Letters Patent.

adapted for folding under the frame, which is adapted to be let down into the recess which is bounded by the ledges 5 and 6 for convenience in packing and carrying.

The frame 7 comprises the track beams 10, rigidly spaced apart by rods 7 and united with a bed plate d which is located centrally in the frame, under the paper 11. Journaled near each end of the frame are spools 12, on which an inked ribbon 13 is disposed, extending over the bed plate and resting upon the face of the type l) in a galley c placed thereon. The spools 12 are provided with a worm or other gear 14, which engage worms or cogs 15, for rotating the spools 12, thereby winding the ribbon from one spool to the other and shifting its position with relation to the type on the bed plate.

The galley c is provided on one side with an angular extension c which is adapted to engage with a corresponding angular incline f on one side of the bed plate. The upper track beam 10 is provided with set screws g which engage a stick 7L for locking type in the galley c.

The spools 12 are designed for optional engagement and disengagement of the worm or other gears by means of the duplex bear ings 31, as shown in detail at Fig. 3, comprising an oblong hole 31 extending in the direction of the spools axis, the breadth of the hole being equal to the diameter of the journal of the spool, and the length of the hole approximately double the breadth.

The ends of the hole at 31 are made deeper than at the other end and adapted to snugly receive the spool journals which when contained therein hold the gears 14 in engagement with the worms 15, but when released therefrom by placing the journal in the shallower end of the oblong hole, the teeth of the worm are disengaged. By engaging the gears at one end and disengaging them at the other, it is obvious that the spools may be caused to rotate to right or to left at will of the operator, the threads of one pair of gears being rights and the other pair lefts.

The paper 11, which is to receive the print is placed upon the ribbon over the type upon the bed plate and held in place as hereinafter described.

A rubber covered pressure roller or platen d journaled at 16 is placed under a casing pression of the pressure roller is Aregulated by set screws 1G. The wear of the rollers is taken up by these set screws. The car-v riage is adapted to traverse the printing frame by means of direct lhand or foot power and to travel along the track beams 10, having flanges 10a under which the rollers on the studs 19 are engaged for holding the impression `roller in Contact with the paper and for guiding the carriage when caused to move along the track rails.

@ne side of the printing frame is pivoted to the case, the other side when being operated is raised to a suitable angle and supported by props as shown in the drawings. This position of the printing frame causes the paper to slide therefrom at each Jiturn of the tumbling rod, the action 'of the one-- fourth turn of t-he tumbling rod -on the paper is illustrated in F ig. 7, the sheet of paper in full lines j .is shown on the paper rests in dotted lines 7c. After a one-fourth turn of the tumbling rod the paper rests 7; have released the paper, which is showin in dotted lines passing therefrom as at 1.

24 are combined :paper rests and paper guides and may be readily adjusted on the tumbling rod by means fof the set screws m. The side pieces a on these rests form the sidewise guides for the paper. This angular position of the printing frame with feed table 28 exactly in front also makes the feeding of the paper with `each hand much easier and quicker.

The feed table 28 is supported in front of the printing frame by means of an arm 29, which is located in a socket 30 on the cabinet 1.

Rigidly secured to each side of the casing 17, is an arm 20, having a curved edge 21, adapted for engagement with the studs 22, for rotating the tumbling rod 23, which carries the worm 15 a-nd also carries paper rests or guides 24, of which there are two, one at each lower corner of the paper, movably disposed upon the tumbling :rod 23, and adapted for adjustment according to the length of the paper being printed, thereby securing perfect registration.

Each sheet of paper is held :by two opposing paper rests or guides while the rolle-r is crossing and the paper being printed, and when the arms 20, engage the studs 22, the tumbling rod is rotated sufficiently to allow the rests to assume a position parallel with the paper. The paper is caused :to slide from the bed plate into the chute 25 and thence to a position lin front of the duplicator. Instant with the releasing of a sheet of paper, another pair of paper rests or guides are thrown into position to support another sheet, each sheet being released automatically after being printed as above explained.

I do not 'limit my invention to the exact mechanism here shown for rotating' the tumbling rod, but I here describe a modification for ,performing the same function, viZ.-A cylindrical body p Fig. '5 rigidly secured to the tumbling rod near its end and having a multiplicity of notches g in its perimeter nearest the carriage, each notch having a :curved side 22 for engagement with 4a stud 21 on "the carriage, which stud by sliding engagement with the curved side of the notch ycauses `a partial rotation of the tumbling rod.

lt is important that the impression roller be rotating when it comes in contact with the paper and when it break-s contact therewith, and provision for this feature is made by the use of a lpair of Contact bars, fmovably seated in the slots 27 in `the track rails and provided with springs, 27a, seated in cavities to hold the lbars in contact with vthe impression rolfler, and by friction thereon when the roller is being moved :cause ythe roller to' rotate. Another method of producing friction for the purpose of rotating this impression roller before it comes in contact with the `type is Ato secure a strip of soft rubber or like material r along the upper surface of the track rails and secured thereto by screws s or yotherwise as shown in Fig. 8.
